HERMAN WONDERLIOH, OF PROVIDENCE, RHODE ISLAND.

SAD-IRON.

To all @chef/:e tt' may concern.

Be it known that I, HERMAN loNDnRLIoH, a citizen of the United States, residing in the city of Frovidence, in the county of Providence and State of Rhode island, have invented certa-in new and useful improvements in Sad-irons, of which the following, with the accompanying drawings, is a description.

' My invention relates to that class of sad irons in which the handle is removable from and interchangeable with a number of cores or bodies and has for its object an improved and simple means of vdetachably connecting the handle with the core body.

ln the preferred form of my invention the handle and connecting device are attached to a shell fitting over the sides of the core or body, but such a shell is not absolutely essential, as hereinafter more fully explained.

ln the accompanying` drawings Figure l represents the sad iron with the shell or cover having the handle attached to the body or core ready for use; F ig. 2 is a medial longitudinal section of Fig. 1; Fig. 3 is a cross section through the iron on subst-aa tially the line a-a of Fig. 1; and Fig. el is a top view of the shell or cover with the handle removed.

The core or body 1 is made substantially in the form heretofore in common use including the smoothing surface atthe bottom Q and preferably provided with an extended edge or bead 3 around its lower edge. This core is `provided with a pin l with an enlarged head inserted and rigidly fastened preferably in the middle of its upper surface, and the head of this pin 4l is preferably either rounded in a vertical plane on top as shown in the d awings or has its top otherwise tapered in order to make it easier to place the shell. or plat attac `led to the handle over it hereinafter explained. rlhe core or body 1 is also preferably provided with another pin or dowel (see Fig. 2) extending upwardly from its upper surface to enter a hole or recess in the shell or plate of the handle.

rlhe handle G is attached to a shell or plate 7 by means of pins and screw nuts 8 8 (see Figs. 1 and 3) the pins extending through the bottom member of the handle and into or through the upward extensions 9 9 of the shell or plate 7. lt will be observed that the handle is thus raised somewhat above the shell or plate. The shell 'l' is preferably made to lit down over the core or body 1 as Speciicaton o Letters Patent.

tightly as is consistent with making it interchangeable with other cores and providing seme slight space for the expansion incident to heating the core without making it impossible to remove the shell from the core. But the shell or plate 7 need not extend as far over the core as shown in the drawings and might be reduced to a plate extending over a greater or less portion of the top snrface only of the core or body without departing from my present invention. Upon the' top of the shell or plate 7 there is provided a slide or guide-way 10 (Fig. l) in which slides a latch ll between the shell 7 below it and the lower member of the handle 6 above it. A. knob or button l2 is attached to the latch 11 Aby means of a screw or pin extending upward through a slot 13 (Fig. in the lower member of the handle; and a flat curved spring i4 is attached at one end to the back of the handle and at its other or lower end engages the back of the latch 1l to push it forward and under the head of the pin 4 when the handle is to be attached to the core.

rllhe plate or shell 7 is provided with a hole 15 (Fig. 2) to pass over the head of the pin 4C and also preferably with a second hole 16 to fit over the pin or dowel 5. It is also deemed advisable to provide a hole in the bottom member of the handle so that the iead of the pin l may extend into or through it. Such an arrangement causes the parts to go together better and more rigidly.

One practical advantage in the construction of my improved device is my particular arrangement of the long flat spring 11i, one end of which is connected to the sliding latch to hold it normally in its forward or engaging position, the Opposite end being carried upward and secured at 18 by the end of the handle retaining bolt. The essential feature of advantage being that the spring is so long and extends np so far from the core that it never becomes heated so as to affect its temper. lt has been found in practice, that by the use of the ordinary coil spring located close to the core, that the same soon becomes heated and after a time loses its temper completely destroying its resiliency. This diiliculty is entirely obviated by the use of a spring of my improved construction.

The method of using my invention is as follows: W' hen it is desired to use the core or body portion for smoothing or ironing, the shell 7 with the handle 6 attached thereto is placed over the core l which automatically brings the head of the pin 4l in line With the holes through the shell and lower ineinber of the handle and permits itto enter these holes. As the handle is pushed down the rounded head of the pin 4 engages the wedged surface 17 (Fig. 2) on the under side of the latch 11 and thereby pushes back the latch against the tension of the spring 14. As soon as the head of the pin d has passed above the upper surface of the latch 11 the spring 1d Will push the latch forward under the head, and the Whole being properly propo tioned Will attach the handle rigidly to the core. When it is desired to separate theni, the knob or button 12 is pulled back with the finger thus Withdrawing the latch from under the head of the pin l and permitting the shell and handle to be again separated from the core.

It is evident that the shape of the pin i may be changed it desired to an upwardly extending pin or projection with a notch on one side only to engage the latch 11, and such a notch has been shown under the Apin head in the drawings, (see F ig. 2). 1llhen a notch of this kind on one side only is used it is necessary to have some means for indicating how the handle is to be placed on the core, and the dowel pin 5 extending upl claiin as niy invention:

In a sad iron, the combination or' a body Y provided with a smoothing surface, a headed pin extending upward troni said body, a detachable shell adapted to tit over said body and pin, a curved plate secured to the shell and spaced from the upper surface hereof, a handle secured between the ends of said curved plate, a longitudinally sliding latch adapted to engage the underside of said pin head located in and adapted to slide in the space between said shell and said curved plate to loch the shell. t-o the body, a flat spring connected to one end of said latch to hold it norinally in its engaging position, the opposite end of said spring eX- tending upward and attached to said handle, and ineans whereby the latch inay be withdra-Wn.
